lets_plot.plot.core.PlotSpec

class lets_plot.plot.core.PlotSpec(data, mapping, scales, layers, **kwargs)

A class of the initial plot object.

Do not use this class explicitly.

Instead you should construct its objects with functions ggplot(), corr_plot(…).points().build() etc.

__init__(data, mapping, scales, layers, **kwargs)

Initialize self.

get_plot_shared_data()

Extracts the data shared by all layers.

Returns

Object data.

Return type

dict or DataFrame

Examples

1
2
3
4
5
from lets_plot import *
LetsPlot.setup_html()
p = ggplot({'x': [0], 'y': [0]}, aes('x', 'y'))
p += geom_point(data={'x': [1], 'y': [1]})
p.get_plot_shared_data()

{'x': [0], 'y': [0]}
has_layers() → bool

Checks if the PlotSpec object has at least one layer.

Returns

True if object has layers.

Return type

bool

Examples

from lets_plot import *
LetsPlot.setup_html()
p = ggplot()
print(p.has_layers())
p += geom_point(x=0, y=0)
print(p.has_layers())

False
True
__add__(other)

Allows to add different specs to the PlotSpec object.

from lets_plot import *
LetsPlot.setup_html()
p = ggplot({'x': [0, 1, 2], 'y': [0, 1, 2]}, aes('x', 'y'))
l = layer('point', mapping=aes(color='x'))
s = scale_color_discrete()
t = theme(axis_title='blank')
p + l + s + t
as_dict()

Returns the dictionary of all properties of the object with as_dict() applied recursively to all subproperties of FeatureSpec type.

Returns

Dictionary of properties.

Return type
